[Freeswitch-users] Does freeswitch forks his processes?

Thu Feb 11 19:15:31 MSK 2016

Without specific details about what the CPU is, how many there are and the

We frown on these load questions because, just like now, it results in
large threads and many people spending a lot of time trying to understand
the parameters.
